In the earlier chapters you have already tested the knowledge about the calculation and method of calculation but in this chapter, you will test your knowledge about the time if you have the skills to check and tell the time accurately and quickly.

If you still need more knowledge about the time and how the minutes are been calculated accurately then this chapter is all about this knowledge.

Once you start to understand the concept of counting the minutes and hours you can check on the times and the time you take to get them ready before school and the time you take to reach your school.

The best way to check and practice is to wear a wristwatch if you don’t have it till now get one because if you have time near to you then you might not get late ever.

There are other activities in the chapter about cooking time I liked that activity because during the cooking while you are watching and calculating the time you will get to taste the delicacies before anyone. You can call it double benefits learning with tasty food and you can tell you are studying if someone asks you what are you doing?

Another topic is also given there in a story form. About a girl who is writing a diary about the newborn baby sister. So that one day when her sister grow up she could read the important incidents of her childhood. This is not some new practice because even these days also people make such memories so that their children can enjoy those memories and understand the happiest moments what they bought to their families.

This is something we do in the video format of clicking the picture but this chapter is not that new so maybe at the time when Rani’s younger sister born there weren’t any video capturing machines or any photo capturing machines available. However, she run her mind and check if there is any possible way to preserve all the memories and wrote a diary. Read the story and help her sort out the dates and times that you have learned throughout the study you have done till now.
